Installation

yarn add @filfox/fnsjs ethers

Getting Started

import FNS from '@filfox/fnsjs'
import { ethers } from 'ethers'

const fns = new FNS('calibration') // or 'mainnet'

// The fns instance has a default read-only provider, but of course, you can set your own provider :
const provider = new ethers.providers.JsonRpcProvider(RPC)
fns.setProvider(provider)

// If you are in a pure node script environment, you may need to use it like the following :
const FNS = require('@filfox/fnsjs')
const fns = new FNS('calibration') // or 'mainnet'
